Installation
STEP 7 Install the Door Bracket
A horizontal and vertical reinforcement is needed for light weight garage doors (berglass, aluminum, steel, doors
with glass panel, etc.) (not provided). A horizontal reinforcement brace should be long enough to be secured to
two or three vertical supports. A vertical reinforcement brace should cover the height of the top panel. Contact the
garage door manufacturer or installing dealer for opener reinforcement instructions or reinforcement kit.
NOTE: Many door reinforcement kits provide for direct attachment of the clevis pin and door arm.
In this case you will not need the door bracket; proceed to the next step.

structural support across the top of the door.
3. Mark, drill holes and install as follows, depending on your door’s construction.
